Questione giuridica chiave
Whether the ordinary dismissal grounds under Art. 12(6) aBPG were met without prior warning
Decisione estratta
No valid warning existed; the contractual clause did not replace the required admonition and the ordinary grounds under letters a and b were therefore not satisfied.
Motivazione estratta
A warning under the case law must have both a reproach and a clear threat function. The employment-contract clause was only a general, abstract condition and did not clearly warn of future sanctionable conduct.
